摘要

Two wild plants Foeniculum vulgare Mill subsp. piperitum (wild fennel) and Salvia aegyptiaca L. were investigated for their volatile oil contents. They were collected from wild population growing in sandy soils near El-Sallum region (41 km eastern Sallum) in March 2000 at flowering stage. Volatile oils from the air-dried plant materials were extracted by hydrodistillation for 3 hr. The characteristic compositions of the essential oils were determined by gas chromatography/mass spectrometry. The essential oil of wild fennel herb was characterized by high concentrations of d-limonene (31.71%), trans-anethole (29.57%), eugenol (5.58%), myristicin (4.61%) and fenchone (4.5%) compared to 22.35%, 31.33%, 4.53%, 0.07% and 8.85% respectively for the same compounds isolated from Egyptian cultivated fennel oil Foeniculum vulgare Mill. The essential oil of Salvia aegyptiaca L was characterized by high concentrations of the oxygenated sesquiterpenoids (43.97%). The main oxygenated sesquiterpenoids in S. aegyptiaca was trans, trans-farnesol, phy-tol, spathulenol and cis, trans-farnesol. In addition to the above mentioned constituents, a variety of different n-alkanes, alcohols, fatty acids, esters and terpenoids were detected which represent minor constituents. The volatile oils showed prominant antimicrobial activities against yeast, Gram positive and Gram negative bacteria at a very low concentration (10μ1).
